The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1a and fig. 1b are schematic structural views of an unfolding state and a folding state of a foldable supporting device according to an embodiment of the present invention, respectively. As shown in fig. 1a and 1b, a foldable supporting device according to an embodiment of the present invention includes: the device comprises a flexible display screen body 1, a driving component 2 and a supporting component 4, wherein the driving component 2 and the supporting component 4 are arranged on one side of the non-display area of the flexible display screen body 1, the driving component can be arranged in a bending area of the flexible display screen body 1 and is used for realizing folding or unfolding of the flexible display screen body 1, the supporting component 4 is used for supporting and fixing the non-bending area of the flexible display screen body 1, the supporting device further comprises a rotating gear 21 and a rack 3, the rotating gear 21 and the rack 3 are connected with the driving component 2 in a mutually meshed mode, one of the rack 3 and the rotating gear 21 is fixedly connected with the supporting component 4, and the rotating gear 21 is meshed and rotated along the rack 3 and relatively displaced to realize folding or unfolding of the flexible display screen body 1.
The process implemented in this embodiment will be specifically described below taking the fixed connection of the rotation gear 21 and the driving assembly 2, and the fixed connection of the rack 3 and the supporting assembly 4 as an example. As shown in fig. 1c, when the flexible display screen body 1 is folded, the rotating gear 21 rotates counterclockwise or clockwise, and the meshing structure of the rotating gear 21 and the rack 3 makes the rack 3 move rightward or leftward relative to the rotating gear 21 (i.e. relative to the driving component 2) on the plane where the rack 3 is located, so as to drive the supporting component 4 fixedly connected with the rack 3 to move rightward or leftward, thereby realizing the relative displacement between the driving component 2 and the supporting component 4. And, the support assembly 4 is further from the driving assembly 2 when the foldable flexible display device is in the process from the unfolded state to the folded state (i.e. the greater the bending angle of the flexible display screen body is). When the flexible display screen body 1 is folded, the rack 3 moves in a meshing manner with the rotating gear 21 and drives the supporting component 4 to move in a direction away from the driving component 2, so that enough storage space is generated for a bending area of the flexible display screen body 1, the bending and extrusion amplitude of the bending area of the flexible display screen body 1 caused by direct folding is prevented from being too large, the storage space is generated, the folding angle is reduced, the bending and extrusion amplitude is further slowed down, and the folding failure of the flexible display screen body 1 is effectively prevented. The unfolding process of the flexible display screen body 1 is the reverse process of the folding process, namely, when the flexible display screen body 1 is unfolded, the rotating gear 21 rotates to drive the rack 3 to move and drive the support assembly 4 connected with the rack 3 to move towards the direction close to the driving assembly 2 so as to realize the unfolding, and the unfolding is not repeated here.
In another embodiment, the rotary gear 21 is fixedly connected with the support assembly 4, and the rack 3 is fixedly connected with the driving assembly 2. When the flexible display screen body 1 is folded, the rotary gear 21 rotates anticlockwise or clockwise, and moves leftwards or rightwards relative to the rack 3 (namely relative to the driving component 2) on the plane where the rack 3 is located, so as to drive the supporting component 4 fixedly connected with the rotary gear 21 to move leftwards or rightwards, and realize relative displacement of the driving component 2 and the supporting component 4 to fold the flexible display screen body 1. The unfolding process of the flexible display screen body 1 is the reverse process of the folding process, namely, when the flexible display screen body 1 is unfolded, the rotating gear 21 moves along the rack 3 and drives the supporting component 4 connected with the rotating gear 21 to move towards the direction close to the driving component 2 so as to realize the unfolding, and the unfolding is not repeated here.
It should be understood that in the embodiment of the present invention, the rotation gear 21 may be fixedly connected to the driving assembly 2, the rack 3 may be fixedly connected to the supporting assembly 4, or the rotation gear 21 may be fixedly connected to the supporting assembly 4, and the rack 3 may be fixedly connected to the driving assembly 2. However, in order to simultaneously realize the relative movement of the support assembly 4 and the driving assembly 2 during folding or unfolding, in this embodiment, the rotation gear 21 is preferably fixedly connected with the driving assembly 2, the rack 3 is fixedly connected with the support assembly 4, and when the flexible display screen body 1 is folded or unfolded, the driving assembly 2 can directly drive the rotation gear 21 to rotate so as to simultaneously realize the relative displacement of the support assembly 4 and the driving assembly 2.
In an embodiment, the support device may further include a bending driving mechanism configured to drive the flexible display screen body 1 to fold or unfold. In a further embodiment, the bending driving mechanism may include a driving mechanism capable of providing a continuous driving force, such as a motor, where a power output shaft of the motor is connected to the rotating gear 21, and the motor provides power, and the power output shaft drives the rotating gear 21 to rotate along the rack 3 and relatively displace, so as to drive the support assembly 4 and the driving assembly 2 to relatively move, so as to implement folding or unfolding of the flexible display screen body 1. Through setting up the actuating mechanism that buckles, can improve the folding or the efficiency of expanding of flexible display screen body, also can save the required work load of manpower folding or expanding simultaneously.

As shown in fig. 2a and 2b, the flexible display screen body 1 may include a first region 11, a second region 12, and a bending region 13 between the first region 11 and the second region 12; when the flexible display screen body 1 is in the bending process, the rotating gear 21 rotates along the rack 3 and relatively displaces, and then drives the first region 11 or the second region 12 of the flexible display screen body 1 to move along the direction away from the driving component 2 while the supporting component 4 also moves. Through setting up rotation gear 21 and rack 3, when flexible display screen body 1 is folding, rotation gear 21 moves and relative displacement in order to drive supporting component 4 to the direction motion of keeping away from drive component 2 along rack 3, for flexible display screen body 1 folding produces sufficient accommodation space, effectively prevents flexible display screen body 1 folding inefficacy.
It should be understood that, in this embodiment, the flexible display screen 1 may be an integral screen structure, and for convenience and clarity of description, the flexible display screen 1 is divided into three parts, namely, a first area 11, a second area 12 and a bending area 13; the flexible display screen body 1 may also be composed of a first area 11, a second area 12 and a bending area 13 that are separated from each other, and the specific structure of the flexible display screen body is not limited in this embodiment.
